This
kit uses the Raybestos frictions. SunCoast has tested and
approved this kit. The IRONpac kits contain the clutches and
steels, with required pistons and pressure plates to stack
the clutch pacs to the max! SunCoast engineered this kit and
we manufacture many key components that make it possible to
hold the torque that your PowerStroke is putting to the ground.
We have assembled the best parts available for your 5R110W
transmission and put it in a kit form to enable our dealers
to build a dependable unit.
